Abstract
En fremgangsmåte for kvantitativ geostyring ved boring av en brønn omfatter et tofrekvens resistivi- tetsverktøy for måling under boring, for å måle de elektromagnetiske egenskaper ved en formasjon på samme tid og sted ved to forskjellige frekvenser, hvilket resulterer i fire undersøkelsesdybder, hvor- ved tilstrekkelig informasjon blir oppnådd for å løse problemet med en forekomst som nærmer seg, i en geostyrings-modus. Det vil si, det er mulig å bestemme verktøyets avstand fra en forekomst som nærmer seg, og det er også mulig å beregne resisti- viteten av denne forekomst. I geostyring er den dybde som er av primær interesse, dybden 'til kontakt med en annen formasjon. Det er tre ukjente i problemet (dvs. avstanden til forekomsten som nærmer seg, resistiviteten i det produserende laget, og resistiviteten i formasjonen som nærmer seg). Dette problemet løses på en datamaskin, generelt utenfor borehullet på overflaten, ved bruk av en enkel ikke- lineær regresjonsplan, for eksempel invertering ved bruk av en modell med en høy fallvinkel, og ved bruk av minst tre uavhengige datapunkter, dvs. minst tre av de fire undersøkelsesdybder, for å løse de tre ukjente som nevnt ovenfor, og dermed bestemme avstanden.
